Does anyone else experience this same thing? If so, what do you do to stay "hyper focused" on your idea at hand?
For the ones that seem feasible, I do a one-page business plan. How would this work, how would it make money, would it be profitable, are there any awesome features I need to write down while I think of them. This gets it out of my head and onto a piece of paper. The paper goes into a folder, and I don't allow myself to think of them again.
From time to time (normally when I get one of them stuck in my head once more, good ideas are like viruses) I review that folder. A quick look now reveals that 3 (of the 7 that are in there) remain good ideas (the others really wouldn't be profitable, though I might try some of them for fun).
Now I must compare those 3 to my current business - which energises me more? Energy is a combination of excitement (where the new ideas have an advantage) and revenue likelihood (Money is energy). I'm in an income phase at the moment (having recently moved my coaching business to the UK), and the income potential of my current business is far greater in the short term than any of those other ideas. So current business wins my energy, and if I really need to validate that in a thinking space I can.
Once I have a coaching income base once more, I will likely repeat that exercise and see if I can take on one of the others. By giving myself permission to have great ideas, and a process to nurture them based on my priorities, I manage to stay more focussed on the business at hand. Certainly, that works better than trying to ignore them (and, simultaneously, remember them for later!) in my brain.
PS - Don't second guess yourself after you've made a decision.
PPS - Don't undervalue the work you've already done on your current project. Execution is harder than ideation.
PPPS - Lay off the coffee.
If you actually want to chat more about this and talk about your ideas send me an email. Im always looking to network with people.
