A piece of advice that's engrained in my mind...
To trust the process is to remove the noise.
Because on your way to a given destination there will be a lot of it.
The noise of other people's opinion, the noise of the voice inside your head - whether that be doubts, regrets, anxiety...
At the end of the day, none of that matters.
The only thing that will bring you closer to your destination is stepping one foot in front of the other, and following the process that is needed.
Of course, we can research, plan and visualise the process - but no amount of any of these will come close to taking action.
Be patient, get your head down, and don't worry about the end result - instead focus on the processes that will get you there.
