Do it now. Make time.
Most people will never start something that has the potential to be life changing for them because they don't want to be seen starting from the bottom.
The fact is that thinking about starting out will see you telling yourself that it is going to be uncomfortable, both physically, mentally and in your own eyes probably visually. More often than not, this is where it all ends.
The reality is though that those perceptions are with you. Not anyone else. Yes you'll feel it but that feeling is just that, a feeling.
People around you will get behind you and support you. People you've never met before will do the same as you move along your journey. There are lots of amazing people in this community. Loads of them, all waiting to cheer you on.
So stop thinking about doing it and do it.
