to begin or not to begin

so in my opinon it is often hard to start things
starting things is sumtimes like jumping into a pool...you hesitate your nervous.. you may have fear or doubt... wut if the pool is deeper then what i expected ( what if im getting in over my head) what if the water is too cold ( what if i don;t like what i've started) and of course what if i can't swim ( what if i fail)
i think however, that if you want a change and if you want something to happenn... something potential great to happen then you need to put all your fears and doubts aside and take that chance...
because what's worse not taking that chance and not starting something and living your life with that tiny little thought that will always roll around in your head of what would have happened... what could have been.... or is it worse to take that chance.. see the potiental good that can come from it.... or u may not get what your wanted from starting something but at least you took that chance... saw it through and you most likely learned something that you can later use in life...
so i will end my saying a very widely used phrase you only live once...
