Consider your options carefully. It is likely that you are expecting top grades in your Leaving Certificate if you are considering pharmacy as a career so there will be plenty of doors open to you. Make sure you do plenty of work experience in different areas of pharmacy and if it is healthcare you are interested in then consider getting some work experience in medicine etc. I know quite a few people who have completed a pharmacy degree only to realise they actually want to do medicine!
Realists are usually interested in 'things' - such as buildings, mechanics, equipment, tools, electronics etc. Their primary focus is dealing with these - as in building, fixing, operating or designing them. Involvement in these areas leads to high manual skills, or a fine aptitude for practical design - as found in the various forms of engineering.
Realists like to find practical solutions to problems using tools, technology and skilled work. Realists usually prefer to be active in their work environment, often do most of their work alone, and enjoy taking decisive action with a minimum amount of discussion and paperwork.
