Be proud not on your gifts but on your hard work and your choices.
You might be really good at math. It might be really easy for you. Thats a kind of gift.
But practicing that math and taking it to the next step that could be very challenging and hard and take a lot of sweat. Thats a choice.
You cant really be proud of your gifts because they were given to you. You can be grateful for them and thankful for them but your choices, you choose to work hard, you choose to do hard things, those are choices that you can be proud of.
