Motivation comes from self love.
The more you love yourself the more motivated you will be to move forward to live. Yes, even narcissists and sociopaths are successful by using this method. They have such self-interest that they will go to the ends of the earth in order to advance an agenda.
This is obviously not a balanced approach, but it is proof that it works. Many of these types rise to the top of material society; for better or worse...Whatever the case if you don’t love yourself to some degree you won’t be motivated to do much. So sit down and appreciate your own life.
Appreciate what the heavens have done for you and what you have done for yourself. It’s all good if you just keep moving forward and never let the momentum of life start to work against you. Push off and jump into a river of life. Let it take you where you want to go. Staying on the shore is no fun...
