When is the right time to retire for me?

My friend has retired about 3 months ago. She says it was the best thing she has ever done and that everyone should retire as early as they can. 

Early retirement question is not standing in front of me right now. I still didn't save enough for that. I will need at least 10 more years. 

Also, I don't feel that I am done yet. I feel that I am not done with going to work. 

If I would leave now, it feels like I am leaving a party which is not finished. Some say, you should leave a party when it is not over yet. 

It may be true for some people, but not for me. I don't like to leave parties early. I usually stay till the end. 

By this funny criterion, I might not retire early because I would want to stay till the end. 

What defines my "end of the party for the work situation"? 

It is not the end of the company I work for. 

It is not the end of the world either. 

I like people I am working with. But when we get new people I like them too. If one of my colleagues retires, it is not the "end" for me. 

It must be something else. 

I like my office, but I will be OK if I will have to change to another one. My office is not the "end" either. 

I like to dress up a little bit and wear my heels (3-3.5 inch). Like these: 

I can wear them because I am sitting at the microscope the entire day. I don't have to walk much. On weekends or days I am off, I mostly don't wear heels, especially when I go to Walmart or to Lowes. 

I have great fun wearing my work cloths. I have a lot of cloths. If I would have to wear scrubs, it would make me sad, very sad. 

Not sad because my cloths would be waisted. Sad because I like the process itself. I like the look of my cloths and I like the sound of my heels when I am walking. I will be missing that at lot. 

Writing this I realize that the business with the cloths and heels might sound very superficial, but that's how it is. Fortunately this is an anonymous blog and I don't have to pretend. 

Also , as Oscar Wilde said once: "The only excuse to be absolutely overdressed is being absolutely over-educated". My Bachelor in design, MS in language and literature, MD and PhD have enough weight to counterbalance my superficial fun with cloths and heels.  

My retired friend said that since she has retired, she spends more money. She has more time to travel and to do other activities. 

There are many articles out there which say that working only one or two additional years will substantially increase your financial cushion. You can work just a couple more years if you think you have enough but are still worried. 

Adjusting it to my superficial situation, after I have enough money saved I will have to evaluate if I already had enough fun wearing my heels or if I continue it for a few additional years. 

Fading of the fun of wearing heels might be a sign for me that my retirement is approaching. I will definitely have to retire when my looks change from this to that:

I know, it doesn't sound like a serious evaluation. This entire post is not very serious. 

I talked to my sister who is a radiologist and she told me that she wants to live to 120. My cut off is much less ambitious with only 102. She does not plan to retire early and she also likes to dress nice.
