First step is always the hardest

I quote from Nikola Tesla:

My method is different. I do not rush into actual work. When I get a new idea, I start at once building it up in my imagination, and make improvements and operate the device in my mind. When I have gone so far as to embody everything in my invention, every possible improvement I can think of, and when I see no fault anywhere, I put into concrete form the final product of my brain.

My ideas are definitely nowhere in comparison with Nikola Tesla but I've been following such patterns since I started working. I've always advised people that the first step is always the hardest.

Personally, that's the part where I'll try to visualize whatever that I'm trying to do before I actually start work. This has been quite effective in helping me focus my thoughts on a particular problem and visualize the alternatives before choosing the most effective one for me. Try it sometime.
