The one mistake you can make is believing that self-doubt is a part of your process.
Spending time thinking that your work isn't good enough, isn't part of the journey. It's a travesty.
Here are all the reasons why self-doubt is ruining your career and how to stop it
1. You're not respecting the journey
If you are making mistakes, early on or when starting out in a new environment, don't beat yourself down. It's always hard hearing criticism but it's not as hard overcoming them. If you could have done something better, hold your hands up. Promise to do it better next time and move on with your life. You would never judge a young person for mistakes in their grammar. Why? Because they are just learning. So, give yourself the same respect.
2. Every outcome you have achieved has come from practice not, self-doubt
Remember that time when you got really lost in self-doubt and then because of that you smashed your work the next day? Exactly, because that never happens. Your best outcomes are based on your repetitions and on your hard work. It has absolutely nothing to do with your self-doubt.
3. Self-doubt makes you rely on confirmation bias
When you lack confidence in your work and stew in self-doubt, you can't help but feel a little guilty because you know it's so completely and utterly counter-productive. So, instead, to justify your self-doubt hole, you start to gather all of the evidence you can to support the fact that you are a failure...!
This is very easy to do but also very destructive - why would anyone in their right mind try to focus on their negatives to better themselves.
Instead, do what your gut is telling you to do.
Stop focusing on the negatives and start fact-finding about your positives. Remember every one of your achievements and wear them with enough pride that it melts all your self-doubt away.
4. Self-doubt ruins your rationality
Think about that spiral of self-doubt.
Think about how quickly it transpires out of control. Making you feel a myriad of uncontrollable negative emotions. One minute you're fine and then the next, well, you're doubting the point of your existence. Does that sound rational to you?
Well, that's because self-doubt is highly irrational thinking based on fears.
Think of self-doubt as the rapper over the sound of your anxious beating heart. It's just meaningless words, based on how your body/mind feels at that time. It doesn't make it true.
Try to be objective when you feel an attack of self-doubt. Imagine it was happening to your friend. Step out of your own thoughts and advise your "friend". There's no way you would encourage them and say "continue with all this self-doubt, it's great".
Well, that's exactly what you should be saying to yourself too.
So enough is enough, forget the self-doubt. Just concentrate on being the best version of you.
