I recognize only one type of failure – a failure of never giving a try. If you decided to give some option a chance and it did not go well or you figured out that it was not the right direction – this is not a failure. This is called – experience. Your experience.
We may have advisors, friends, mentors or colleagues, whom we can ask for advice. Their recommendations will be valuable, but only to certain extent. Because each of us is unique. What works for one person, doesn’t necessarily work for another. And it’s OK.
Hence, the only way to find your way in life or career, is by trial and error, by correction and adjustment of the path. Which means, we need to keep trying and experimenting as many times as necessary. Until we finally figure it all out.
This is the principle I follow. This is my life compass: it is always better to try, than regret later of never giving it a chance.
