What his/her told you? I’m curious to know.
But, anyways. the fact that you haven’t gotten your goals yet, it doesn’t mean you are not gonna get them in the future. Or maybe, even some of them.

Most of people don’t get all the goals because several circumstances and psychological problems or a syndrome make it very difficult, it’s very understandable to be one of them, or at least, to delay this achievement.
Said that, focus on enjoying the way to these goals. If you are able to do that, the probability you get your goals will be closer. Or even along this process you can even discover that your real goals end up being a little different ones that are similar but a little different and full your life as much and the first ones could do it.
Also take into account that if you have a lack of self-confidense, you will find more obstacles in the path and with every obstacle you overcome you will get more confidence and even s
discover new things to do that might mean you are very good at doing.

I want to encourage you. And take into account the process is what counts. Your level of motivation, knowing your flaws because of any handicap you might have. Everyone have handicaps of one or another nature but they feel a failure to not achieve their goals or all their goals. Many they feel less lucky and suffer more than the person who enjoy the progress, who is able to reinventing him/herself is more happy.
