Diversification in this case means quantity, while specialization means quality. And between both, quality is desirable. Quality brings better results on long term, although you have to be patient until seeing progress.

The quality over quantity tends to pay off in the long run especially if you have the patience to wait for progress. Diversifying too much can increase risk while concentrating on the most promising projects can help minimize uncertainty.
