Good advice on how to get started on that project / hobby / adventure you have always want to start can be found here: How to Dare to Begin.
Beginning is often the biggest hurdle. Before you begin, you can imagine all the difficulties you will have, and such imaginings stop you before you can even start. If this applies to you, read the article. You may find yourself getting started after all.
Another thought: take an athlete’s approach to getting started and keeping at it. Get a coach. Get cheerleaders. Talk it up while you are doing the thing you’ve held off doing. Give yourself as much encouragement as you can. Give yourself a goal. Do all those things and you will find you not only get started but you keep going.
Good luck. Dare to do good things. Great things, eventually.
