as for 取得, the emphasis is on the result, it means you have "got something", not "given out". And it is usually used before an abstract thing like success, sb's trust. 取得 is very similar to 获得。
as for 实现, it puts the emphasis on the process. it means you gonna do something to 实现(impelement) your goal, your dream, and so on which you have not got yet and need your effort to achieve. So typical example sentence is : 为了实现我的目标/理想/计划,我(将来)会更加努力/我(将来)会花更多的时间。
by the way, it's been a long time I haven't been here, and Qmmayer you are the only one in my friend list who is still learning, impressive perseverance:)
