“Just keep going”, Elon Musk
Whatever you do in life, you will face setbacks, problems, difficulties, and hurdles. That is just part of the learning process. The path to success is littered with problems and difficulties. A child finds many ways of how not to walk before it starts walking. The same is true for learning everything else. You learn many ways of how not to do something before you find a way that works. If you get demotivated by problems halfway and give up, then you will never succeed.
Regardless of what you are trying to achieve and the kind of problems you are facing now, remember, that the only way to succeed is to “just keep going”.
