Easily frightened​ by complexity

Question

Though I'm not this much bad programmer and I can do it but still when I see a complex code and don't clearly understand every bit of the code, I get easily frightened.
Apart from practice what else can I do to overcome this situation?

Answer 1

If you're trying to figure out what a complex piece of code does, work your way through it line by line. If a line just doesn't make sense, copy and paste it into Google and chances are you will find a lot of useful information about it.

Answer 2

One of the most important things in all "scary" situations in life is to relax and concentrate before taking the challenge.
If you're tired, stressed, if your back hurts or anything like that, it will increase your stress level and make things more complicated than they look. Take a nap, grab a drink, stretch out and feel relaxed and awake. Then you can look the code with new eyes and realize "I can do this, with or without Google/etc. Heck, I WANT to do this!".
Good luck on your programming career! :)
