The thing about ambition and achievements is that they are many times measured based on others’ performance and not just your own.
As long as you keep the measurement just to yourself, you are happy and good. You’re working towards your goal. If you achieve it, that’s your hard-work well-earned. And if you fail, you learn from your mistakes.
But, as soon as you start looking around you, at other people, their achievements, their growth charts, you start creating problems for yourself. Jealousy, envy, underplaying your achievements, all come into play.
None of that should matter. The more time you spend delving on those things, the more time you waste. You can’t change their lives. You surely are impacting your life by these negative thoughts. You worked hard, honestly and you earned your achievements. That is what matters. And that is what you should remember.
Life is getting above the negative thoughts which rise in your mind/heart and concentrating on the positive ones which want to grow more inside you. And, soon, the positivity will envelope you in such a way that none of the negatives will impact you any longer.
