Your dream about the future is good. Its always good to live outside your comfort zone. Moving to UK with your kids having a good education there is a thing that all Nigerians wished for, but the means of relocating is the major challenge we are having.

Secondly, Onions business is a good one if you can do it in a big way as you wish but i will advised, you start from small and grow.

I like your mindset and since you can dream it, definitely you will achieve your goals. I wish you the best of luck.
