I shall be brave and put my tin hat on :)
As I understand the context of what you're trying to say, I would say this ...
Every job that you do should give you both a sense of satisfaction and value. From that, you are enthusiastic to do the job to your fullest ability. I believe that if you work with passion and commitment, this will lead to the job being done well and you being appreciated. I also believe it is important to do a job which allows you to develop your personal skills and work well with your employer. I firmly believe that, in doing work, you should be happy and enthusiastic.
This is not a direct translation, it doesn't sound 100% authentic (but for a non-native, it'll do), and without context it's difficult to say exactly what you want, but I think this is what you mean. However, if you use the above, you better make sure you have the oral skills to go with it ...
