Your target is not realistic but possible ( sorry ), too high and need high skill and time to be done. Most people will say, get out if the price reach your target but some people decides with " almost " is enough. Another opinion is, get out when the price reach your stop loss ( cut loss ), meaning we have stop our activity to minimalism our loss. Time is relative and patience is needed, do you have it if must wait & see until 5 or more years? I believe you don't. Change your plan, fix your strategy and good luck to you.
