Not all ideas are worth pursuing, but for every idea you come up with, detoxify yourself of all selfish reasons and you’ll realize if you still have the inner nudging to turn a particular idea to a seed worthy of the investment of your time, your resources, your energy, your legacy, your integrity and your values.
Get your motive right and clear from the get-go and every other thing will be just a little extra (sometimes a bit more) than a walkover.
