Whatever you want to do, it's important to have a motivation to support you. It can give you power and confidence when you need.
Have you ever felt it's no valuable to do something although you have done it for a long time. Sometimes you don't know why you do it and even doubt whether it is right that you choose to do . You suddenly feel lost.
In a situation like this, don't need to think too much. Thinking too much just makes you more confused.
You just need ask yourself: why I choose to do it and what was I want to get most. Then what is the most important thing I need to do and write down a small goal for you. Finally, just to do it. Action is your greatest motivator.
