You don’t have to know it all to get started, you just need to know what the next step is. If you wait until you have all of the information or until you know exactly how things will play out, you will be waiting forever. There is risk and uncertainty in everything we do in life. There is even risk and not taking action.
Determine where you are currently and where you think you want to be in the future. Once you have an end result in mind, then reverse engineer the next steps to get there. You don’t have to have everything planned out to a “T” to get started. Have a general guideline or a framework on how do you think it should look and what you need to do to get started. I guarantee that how do you think it looks and how it will eventually end up working is going to be at least a little different. But if you don’t do anything, if you wait for all the answers to come to you, if you wait for certainty, you’re going to miss your opportunity.
