It is ok to level down, it is ok to downgrade, it is ok to look like you're weakening a little bit, there is nothing wrong with that. It doesn't mean that you're really getting weak, you're just doing lesser things today to do greater things in the future.
If normally you can make 200 push ups a day but today you really can't do it because your back is aching or you are experiencing a little fever... Just make 100 or even 50. It is not about making excuses. Making excuses means not doing anything. You still do your routine so you should still be proud of yourself, you need to do it less so you can recover from illness.
If you can send your children to private and exclusive school before but suddenly your business is going down for whatever reasons, transfer them to a cheaper school. There is nothing wrong with that, your life will become worse if you will still do what you can't do anymore. You can transfer them back once the earnings of your business returns to normal. You need to get a breathing room so that you can move freely, you need to give yourself a little bit of a rest so that you can come back stronger.
Sometimes you need to accept that you are getting a little bit weaker so that you can have an easier life. A lot of people were so full of pride and they can't admit that they can't do something anymore. They want to prove to other people that they were still strong, rich, deserving, capable and has a special place on earth.
It is ok if you will step down a little bit, it is ok to take things lightly a little bit so that you can prepare your body and mind for a big comeback. Just learn to enjoy the rain for a while and wait for the sunshine to come back.
