worrisome_dad:
When my friend was retrenched from her managerial job, she ended up working in temp/ contract positions to provide for her family. Then suddenly one day, she told me that she is going to set up a tuition centre with 2 partners whom she barely know and it was the passion to be her own boss and help nurture the next generation that made her determined to enter this joint venture. Her family gladly invested 5 figure sums into her new partnership.

I guess that was the key mistake your friend made, regardless of whether it was about setting up a tuition centre, or any other venture
