The sad truth is friends and family are the worst detractors.
They’ve got the most to lose if you change or progress so they like to keep you in your place.
It’s not even a deliverate thing most of the time. Just a weird passive resistance. I’ve had it lots. Once you start to realise that even your best mates or parents will try to curtail your excitement about ideas or plans, the easier it is to dismiss them.
I do it too. If a friend goes travelling or makes a bold life change I get jealous and it makes me uncomfortable. But it’s also a problem with me, not them. In fact, their ambition pushes me along.
Anyway basically don’t listen to other people. Other people know shit all about what you want or what you’re able to excel at.
