It’s really important that you realise that “failures” are a necessity in experiencing success and happiness. I aim to fail as often as possible. But what’s important is are you taking the time to learn from your failures?
Firstly you need to completely change your conditioned understanding of “failure”. You need to embrace it. Then most importantly you must focus on learning from each “failure”. Otherwise you’ve missed a valuable learning and growth opportunity.
You thrive in every area of your life from the ongoing failing/learning process. It doesn’t matter if it’s your relationships, body/health, career/business or financial situation. Fail and learn as often as you can. Just make sure you take the time to learn. Otherwise you repeat the failure.
