Don't compare your beginning to someone else's middle. They had to start somewhere too.
Be careful you don't see the result and forget the effort involved to get there. Don't look at a body and think I wish I had those muscles or that weight loss. That person has achieved that result with hard work and action. It's easy to look at pilots and say what a dream job, I wish I could do that but it seems so unachievable and out of reach. You absolutely can achieve a flying career, your dream body, what ever you set your mind to, you just need to put the work in. You may think the grass is greener on the other side but if you took the time to water your own grass it would be just as green.
The first time I ever learnt about flight was during my military recruitment. I remember feverishly penning the definitions of an aerofoil, people around me had done civilian qualifications or come from engineering degrees and I did dance and drama in high school 😳 no senior science subjects and had no idea about the laws of physics. I didn't feel like I was learning, I felt like I was surviving but struggling to stay afloat in a whole new world with a whole new language that is aviation. I was drowning in the experience but treading water for dear life to hang on. I felt I wasn't good enough, that I couldn't do it. When I was younger and I found something hard, I immediately questioned myself. I let the doubt of others get into my head and run my thoughts of insecurity. Now with experience under my belt, when something is hard, I don't for one second think I can't do this. I know I can do this, how hard it is has nothing to do with my own ability to succeed, it just means I have to work harder until I can do it. Every time you start a new skill it will feel hard, it will be frustrating because you're a beginner. As time goes on, the more you practice and work the easier it gets. Eventually you'll look back and laugh at how you ever found it hard in the first place. Every adventure requires a first step, believe in yourself, have a go and when things gets tough, hang in there, you can do this!
