I started programming in 1991. Initially I didn't understand any thing. Then after couple of months every thing made sense. The only thing in programming is practice. If you don't get 100th time you should try 101st. If you don't get it in 1000 times try 1001 time. The only way you can get any thing in programming is practice practice and practice. This is not rocket science eventually you are going to get it. The only thing you require is patience. Always start simple. Then slowly try to learn harder things. These days you have lot of resources available online which makes it very easy for one to learn programming
