I am in a similar position, in that I have very limited capital to put into shares and only buy into 1-2 at a time.
Please note I am very new to this and so this is in no way financial advice but the main points I have picked up relevant to my situation:
1) Bank the 25%+ profits when you can, I have regretted selling too late more than I have too early..
2) Don't rush your decision on buying stock, and take as much time researching as you need until you are comfortable with your trade and entry position.
3) If you have the option of contingent trades, use them so when you buy a stock you have your sells orders already set up for a stop a loss or cash in a profit - this has helped me not trade on emotion and set realistic goals for stocks.
