Yes but to become truly good at what you do you need to improve on the things you suck at. Even if you truly suck at them, giving up is not the answer. Its often easier on your teachers o give up tough after a point.
Ive been teaching a lot of 60-70 olds to use computers and even they get there in the end so i dont really see anybody as lost cause. Atleast i dont have to teach you how to use a mouse.
I find that bad computer use and miss focus are equal to each other, so just like drawing in life class is about observing whats really there so is learning computer use. The trick is to do things at a pace that you can recall the exact steps you took to get somewhere. Often when I ask normal users what they did they have no clue, or no confidence in what they did. Why is this important? Well computers are VERY literally minded which is the problem. They dont work on what you intend but what yo really really do.
Now its been established that you dont have the intuition to use a computer, so you must solve the problem in a more logical way. This path is slightly painfull, but you will come out the other end of the tunnel smarter then your peers.
First step is to relax with the computer, you will get it worng the first 100 times but take a seat above yourself and observe what it is you really do. Not what you think you do.
Getting told negative feedback is healthy, it forces you to rethink wast areas of your being. Taht's a good thing, use the info.
