Love - a very strong feeling of liking and caring for somebody/something
Admiration - a feeling of respect for and approval of somebody/something
What it means is love has deep emotional attachment than admiration does. That's why when we lose somebody/something which we love, we tend to fall into mental depression. Ideally you are not going to achieve anything by depression.
So, in my opinion if you want to have healthy mind, you should more admire than love the things/people/events/topics/etc. That's my opinion by the way!
