Would you prefer to learn by reading instructions, watching someone else perform a task, or by doing it on your own by trial-and-error?

Wel all three. it depends on the instruction or skill.

I am a visual learner and like to see things in practice.

Always trial and error when it comes to learning by myself

I prefer reading instructions and observe some else perfomring the task

when trial and error comes we will start learn quickly and the most impotent thing is we will never depend our self on others we will do what we want 

Reading and watching instructions

naturally human get more clear understanding by observing others doing a task rather than just reading instructions of doing that task. because when we observe we use more senses to get that information. while when we read our brain gets information just by our eye-sight.

i would prefer observing other doing a task to learn that task but surely there are some tasks that can not be learned untill we perform that personally so it also depends on thenature of the task. 

by reading the instructions we can obtain a frame of the task. Seeing the task done by others will help you to reduce the errors when you are performing your own. there is no experience bigger than on hands experience in a task.

I am interested in reading instructions and by doing myself.

I strongly believe that failures are the footsteps to victory.

Practise makes a work perfect

Works done by myself gives me confidence

i prefer reading instructions and applying them in the correct manner as possible
