i'm a beginner and i'm thinking of investing say 15- 20k in shares and growing it (will put the money in gradually when i'm ready to buy more and more). i don't make much money (trying to get a job, but got disability issues), so my income might not be much. i plan to keep adding my money into shares to accelarate growth. if i study it all - been reading and learning heeps - can i expect to do a decent job of it myself, or will i get much better performance if a professional (adviser or broker) does it all for me and picks out all the shares and amounts. i'm looking for an aggressive approach to shares, but carefully managing my risks. or maybe the total price for him to do it will be too much -a few $1000?- and because of that i'm better off doing it myself, as i'm willing to learn alot and spend the time. i'm aiming for solid returns each year (10-15%? or something). your advice is much welcome, as i'm wondering what kind of benefits or cons there are to getting a pro to do it all for a beginner like myself, rather than me doing it all.
