Do you mean support in general, personal support? Or just support in the form of YouTube views, likes, etc.?
If personal support - this basically comes down to the people you surround yourself with. If you are growth driven, and your friends and family aren't, this will eventually create a gap that they just can't understand - they won't be able to relate to you, and won't see your vision or "get" why you have the goals you do. When that happens you can't expect them to support you, you just need to bring new people into your life. Be around more people who are where you want to be, and who have the same drive and determination. Not saying you need to shut out your family and friends, but you'll find that you'll only be able to engage with them at a surface level, and maybe for less time overall in the month/year as you'll be focussed on business goals.
Being part of a good business coaching community can really help a lot with the motivation, accountability and support side of things!
