how to get started on developing my own project?

Question

i have an idea for c# program that im trying to create. so far ive written "specification" for it (purpose of the program, few user cases) - is it the right way to start a project? if so, what should I do next?

Answer 1

This will help you outline your project:

Also, I personally use https://trello.com/ to keep track of my projects or write down any new ideas that come to my head that will improve it. If anyone has some other tips feel free to share, planning is a very important step.

Answer 2

and what about starting to code a documented idea? should i design all classes first, or maybe design database for the project (the one i have in mind is a personal finance/budget manager)? when i think about it, it seems so complex project that i dont know where to begin
PS i checked the trello site - it looks pretty helpful with task management and brainstorming ideas :)
