I could take twenty. The money would be better and the work would be easier.
But this isn't a class. When I take someone on, I'm reading their practice, listening to their recordings and rebuilding their plan personally — and then sitting down with them at the weekend to work through it. Five is the number where I can still do that properly. Six and something starts slipping.
It also means I have to choose. I run a placement test before I say yes, because I'm not going to take 150,000 rupees from someone if I don't believe I can get them to their target by their date. If a course would do the job instead, I'll tell you that — and you'll keep the difference.
