My free advice: Be passionate about what you do. At the end of a really bad day, it’s the passion about your craft, that will bring you back to do it all over again the very next day.
I work a full time job, and do cakes as a part time job. I have worked 50 and 60 hour weeks for 21 days at a stretch with no break. I am up at 5am, go to work all day and bake all night. Then I get up and do it all over again the next day, and all weekend long. I am thankful my children are grown and my husband has been totally supportive. I am passionate about what I am doing. I am nurturing my business along like it’s a new born baby. Many of the people I have spoken to, who are in a small business have said the same thing. It’s a learn as you go process.
If this is your dream, go for it. Dream big.
Good Luck to you,
