I usually dont have time to monitor investments my self so i usually invest as sleeping partner in others business who are good at there job, but I am also in same trouble, I have few suggestions but do it with very caution no zimadari of mashwara giver 
1 - Generally, Invest in business with some one where you see opportunity window, I have invested as a "sleeping partner" in metal re-rolling mill for last 3 year and had a very good return, recently I moved finance to aluminum alloy wheels inventory.
2 - Invest in stocks/Commodities through finance managers who are best at investments, make an agreement in profit sharing on the basis of "no loss basis may be less profit" so he plays safe with your investment, I have worked on 30/70 division on play safe no loss.
3 - Invest as sleeping partner in food business if you have some one in circle (best if you are in lahore)
4 - real state
This is purely coming from my experience, please share if you have some ideas so far.. will be glad to hear.
