Why not leave it to the experts?

Most posts are in favour of direct investing…and even I am also mostly invested in direct stocks, still I would like to point out other side too to make the discussion balalnced request @ChaitanyaC , @Investor_No_1 , @royatirek , @hardik_shah1 …Request you to give your views…

1. Most important part is , we are on a learning curve and everybody has their own idiosyncrasies. We may become acceptable investors ( I mean , who can generate decent returns) over years, But what will happen to our hard-earned capital till the time we become more balanced and level-headed investors? What if we lose our capital to large extent, while making costly mistakes and learning the nitty-gritties of the game?

2. When we leave it to the expert fund managers, what we are essentially doing is at least ensuring a mediocre performance instead of our learning curve performance. Definitely they have their own compulsions and problems, at least they have enough resources and motivation to come out with mediocre and acceptable performance.

3. There is also an opportunity cost involved. When you are learning the tricks of the trade, studying past market behavior, different strategies, may be the same time and effort applied in your active profession, will render more benefits than the probable alpha seeking?
