It's not even everyone else's opinions that get to us it's our own. Because in anything that we want to do an actually want to do it and have no doubt in our mind that it's for us. no matter who says what we still do. From relationships to business to personal goals to accomplishing dreams. The moment we start to doubt ourselves and if we can do it or if it's for us is the exact moment we back down and don't do it. Why? Because living in the current situation is familiar. Trying to step out and actually try to succeed is unfamiliar it's different unknown. We stick to what is familiar even if we hate it but we are so afraid of the unfamiliar the unknown even if it could lead to success. That's why we don't because we don't know how things are going to end up so most aren't willing to risk it they will stay stuck in the same situation or not go after a dream because of fear and doubt of ourselves not because of what others think but because what we think ourselves.
And those people who tell you that you can't do it, are actually scared that you will.
