When my children were young I did both online and offline jobs in order to be flexible with my husband and children's schedule and in order to be a stay at home mom. My family and friends didn't understand it then and still don't; that's been about 14-15 yrs. ago I think. I was criticized, questioned, and challenged regularly, but I knew I was making money so I continued on that path.
What I learned:
Your dream, is YOUR dream.
Live it, enjoy it, conquer it.
Just because people don't understand something doesn't mean they're right about it. Take the information people give you, think about it, analyze it and make tweaks where needed but keep your dream right in front of you and don't give up unless YOU decide it's not for you.
Don't take your eyes off the dream and goals.
Keep on keepin' on.
