It's hard to end a hobby, especially a hobby as addictive as this one where selections seem to be limitless. However, it's definitely possible to be on a hiatus, I'm speaking from first hand experience. I took a 3 year hiatus from this hobby due to personal reasons and life changes. I have not bought a single fragrance within that 3 years. However, I got into another hobby (and lived out my once high school dream) - modifying cars. That hobby was even more costly lol and I realized how much I could have saved and used that money towards things that were more useful.
Now that i'm married and wife is expecting, the car hobby just doesn't fit into this stage of life. Hence i'm back in this frag hobby to release some stress, this is aromatherapy at its finest.
I can say that my nose has matured through out the good times of this hobby, and I was able to downsize from 60+ bottles to 20 bottles. I agree with lots of BNers about swapping samples to keep the interest alive while saving money. I've done lots of swaps since I reconnected with this hobby, samples are my best cure for craving a new bottle. I now have more samples than bottles. Variety is key (as to many other hobbies), but this might be a temporary solution. And really, I agree with the ones that say bankruptcy can end any hobbies, or when life throws you a curve ball. But I think over time, most would develop some kind of self control and consciousness because eventually, we all have to go back to reality one way or another.
