A man cannot be comfortable without his own approval. There is nothing more satisfying than that sense of being completely "at home" in your own skin. When you achieve that as a natural state of "being", then you can finally look beyond yourself and fully contribute all your talents to the world.
Time cools, time clarifies; no mood can be maintained quite unaltered through the course of hours. When you make a decision to "be" a particular way, you can count on change and external circumstances to come along which will challenge that decision. Remain vigilant after declaring a major decision and manage yourself in relationship to the goal. Set up structures that support you staying on target.
Keep away from people who try to belittle your ambitions. Small people always do that but the really great make you feel that you too can become great. When you are seeking to bring big plans to fruition it is important with whom you regularly associate. Hang out with friends who are like-minded and who are also designing purpose-filled lives. Similarly be that kind of a friend for your friends.
All you need in this life is ignorance and confidence; then success is sure. You can "already know for sure" things that could actually impede progress. Always be on the lookout for the things you did not know, that you did not know. Secondly, work on strengthening personal belief that a particular will be achieved regardless of any adversity that may show up, or evidence to the contrary.
I have spent most of my time worrying about things that have never happened. Worrying is not an action! In fact, it is action that alleviates concern and dissipates worries. Take more actions when you feel that worry is creeping in to steal your time. It need not be a huge action, any action in the direction you want to go will do.
Don't part with your illusions. When they are gone you may still exist, but you have ceased to live. To live a fulfilled life, we need to keep creating the "what is next", of our lives. Without dreams and goals there is no living, only merely existing, and that is not why we are here.
