There are times, we are so stressed out that we go into a self-doubting mode.
We start thinking, if everything we do, the hard work, the management, the money we spend, the sacrifices we do. Are they really worth?
These kinds of thoughts come when we start treating life as an achievement. I would like to tell you life is not a trophy you could achieve in your twenties and thirties and keep it in your house for rest of your generations to see.
Do not think does anything in life matters.
Whether it does or does not. If you do it. You gain XP levels like in a game which no one can take it from you.
Life is a journey. It flows with time. There are good times and bad times. None of them stay forever.
Whenever such thoughts come, just give them some time. They will go. Move on. Keep working towards being a better person each day.
