We are all like peddlers; if everybody would believe in what they're selling, they'd sell all their merchandise at a premium price. A salesperson can't possibly sell his or her own wares if he or she doesn't believe in the quality of their own merchandise.
The same goes for our own prayer and Torah. If we'd believe that Hashem derives limitless gratification from every word of Torah that we learn, we'd be plowing away in Torah all day long. If we'd believe that Hashem stops everything He's doing to listen to the voice of a person that prays to Him, we'd be praying with super enthusiasm; people would flock to the synagogues, and nobody would have to tell the people to stop the idle chatter. If you had an audience before a great king, no one would have to tell you not to talk to the butler at the same time. A person would be crazy to do so.
As such, we put little effort into Torah and prayer because we don't believe in their power, and we don't believe in our own power...
With self esteem, when you realize that every minute of your life is important because of what you're capable of accomplishing every single second, is it logical to squander time. When all the money in the world can't pay for the smallest mitzvah, is it wise to chase money?
One of the things we look forward to in the full Redemption of our people is the restoration of our national self-esteem, when people will be proud to don the crown of Torah, speedily in our days, amen.
Ain od milvado-there is nothing other then Hashem. We have to be aware that the only true eminations in this world are coming from Hashem and everything else is an artificle distraction from true reality 
No good dead or thought is small or insignificant. Good deads effect our netzach, our eternity. The proper understanding of the reward for a mitzvah is that it will benifit a person eternally. Even the smallest sliver of eternity is priceless, so therefore the smallest mitzvah is priceless.
This Beracha is said as an expression of gratitude to Hashem, for the marvelous structure and functioning of the human body. In this Beracha, we acknowledge to Hashem that the properly functioning, healthy body is a marvelous gift from Hashem to man. 
Every Jew is like a letter in the Torah. One who culls another Jew is therefore ruining the Torah scroll, because one ruined letter renders the entire Torah scroll unfit...
When you think of what your personal goals actually are, there is always some degree of tension between what you want to be and who you are. Going into the never-never-land of pretending that you actually are the person you would like to be takes a toll. You have to face up to your imperfections, and most of us respond to that with guilt, and ultimately with resentment. The other alternative to some seems to be to look at the goal as being so far away and inaccessible that it isn't worth fighting the good fight to get there. 
Why do we make a Purim Seuda, when the source of the problem on Purim was that the Jews went to the Seuda of Achasveiros. The answer is that when the Jews did Teshuva from Ahavah. it was counted as if they did a mitzvah and not an aveirah. This shows us not just the importance of Teshuvah, but that physical things can change from spiritual realities.
The Chofetz Chaim teaches that speaking negatively of an older sibling, a step-parent or, God forbid, a father or mother, is not only loshon hora, it is a violation of the commandment “Honor your father and mother (Shemos 20:12)”. There is also a curse applied to children who show parents disrespect: “Cursed is he who degrades his father or mother” (Devarim 27:16).
Yeshayahu- Isaiah - Chapter 19
Hillel says: don't trust yourself until the day of your death. Rabbi Kirzner ztl says that we have to realize that it is the general nature of man to decline. If we are not working on our spiritual growth, we will be sinking. We can never sit back and rest on our accomplishments. Growth is a process and not a destination.
