What do I care about the nonsense that I told yesterday? Ideals and goals can change throughout life. You can preach vegetarianism today and become a master butcher tomorrow.
There is a devil sitting on my shoulder. You are a human being and by this very fact vulnerable to seductions of all kinds. Others know that and can try to make you trade your principles against money. Keep the faith, hold the line, and be strong.
On your own Account
If you want something to be completed, you need to do it yourself. This is sad but often true. Usually you cannot rely on others. Hence, many people act on this principle and have difficulties to delegate stuff. They do not trust anyone else to manage a task and thus cannot let go. Just bear one thing in mind: You are no island. In this world, you will never be successful running solo.
