Ideas are the most difficult to finalise upon. And then, choosing which one is the best, is further a task.
Now, when you are thinking of something, pen down your first idea & scrap it forever. Now further explore your ideas, some might be common, some too futuristic / ambitious & then the one that fits just right.
The best idea is not the one that is totally new or never thought of. The best idea is one that gives you the confidence to stand besides it. Another factor that’ll help you decide is the feasibility! Time is a constraint, always. Look out for things that you’ll be able to finish in stipulated time, look for things thta are fresh & combine an added functionality. The world is getting more & more simple day-by-day. Choose something that is not complicated & original. Choose colours that’ll soothe your client & offer him something more than what he is expecting.
Remember more is good, but not always. Do not overdo things. Keep is simple, original & awesome !
