On this, my 300th Ted’s Tip, a very simple thought that can have big impact. Do it! If you want to run that marathon, train for it. If you want to write that book, start. If you want to build that house, plan for it and do whatever you need to do to make it happen. Don’t wait. If this last year taught us anything, it is how precious & fragile life can be. So push your fears/hesitation aside, as well as any worries about what others will think, and do it. You never know until you try. Plus, the real joy comes from the journey all along the way of trying to achieve your goal. Finishing it is the cherry on top.
