Don't care about what others think, just do what you think is best
Don't let the fear of what others will think dictate the course of your life.
Obviously this can lead to delusion - and sometimes being corrected by others is a good thing - but if you are true to yourself, your principles, your values, and what you think is right, then just do it.
We fear other's opinions for no good reason
If we were alone in this world but still had to creative capacity to do what we wanted, what would we do?
What would you create?
Why aren't you doing that now?
Is it because of fear of what other's will think? Are there opinions justified or more valuable than your soon to end transitory existence?
Most likely no.
Turn off the part of your brain that worries about what others think
It can be a deliberate conscious act to just turn off and eliminate the feeling of caring about what others think.
Or if you have the stomach for it, to welcomely eat the feeling up and enjoy it for what it is.
Accept that it's there, but don't care. It's minor. Insignificant in comparison to you living the life you desire.
You owe it to yourself to not back down
The second hardest part is getting started. The hardest part is to keep going.
A burst of motivation may spur you to take a leap forward and put yourself out there. But the moment you receive negative feedback, you'll want to turn tail and crawl back into your den.
You'll want to cast aside all your dreams to avoid the discomfort of being disliked.
And you'll keep living this way for decades until you die with nothing.
You'll die an unfulfilling life shackled to slave-like servitude of social standards and expectations.
Sounds goddamn awful.
Keep going no matter what, resolutely
Once you've committed to yourself to be yourself, don't back down.
Keep going, no matter what.
You owe it to yourself.
Eventually, perhaps, you'll adapt to the discomfort and it'll suddenly become an okay, manageable thing. It'll become habit, second-hand nature to be this way.
Once that is accomplished you are golden. Your life will now flow smoothly and you will live without regret or shame.
TLDR
Do what you believe is right and ignore the opinions of others. Don't live life in fear of what others will think. This is a tragedy.
