A good piece of advice I can give you all is that if there is something you want to get better at, then keep practising it. This goes for most things..... you want to be a better painter? Paint more often. You want to be a better runner, then run more often. You want to be a better baker? Bake more often. You want to be better at a certain subject? Then study it more often. You want to be able to eat chocolate without guilt? Eat more chocolate. You want to be able to do pull ups or push ups? Practise them more often.
As they say, practise makes perfect. You don't get better at something you don't do.... I mean some people are lucky and don't need to study but get top grades or can play an instrument with little practise. They're lucky, but for most people.... If you want to get better you have to do more of it/practise more often.
When there are things you know you need to get better at,for example when I was studying french. I wasn't good at it but knew I had to improve. Then I had to practise french almost everyday and it resulted in that I passed the course and got better. A few weeks ago I couldn't do front squats but I kept practising and now I can do it with 30kg. Usually when there is something you aren't good at you are hesitant to practise it because you know you aren't good, but progress is the best thing. Seeing yourself improve is one of the best things ever and knowing that you are getting better at something you once weren't so good at is even better!!
I also want to remind you all that to overcome fear foods you need to keep eating them over and over. Not just try them once, but practise eating them until they are no longer fear foods. Practise makes perfect ^-^
