Stairs are a practical way of overcoming a difference in height. You overcome the difference in height step by step - whether up or down. In the vast majority of cases, you also have a good foothold, so you can step safely and firmly, which is helpful when ascending and descending and protects you from unintentionally slipping. However, there are different types of steps: those that feel ideal for your own stride length, others seem difficult because they are either too high or too shallow and deep. It's like life: Sometimes things are going great, at work or at home: you achieve the goals you hoped for comfortably or even faster than planned. And then sometimes you feel overwhelmed, too much is demanded of you at once or things go too slowly and you get tired. In the example of the stairs, it's clear: you won't stop, you'll just keep going, even if it's not ideal. Perhaps this also motivates you for a corresponding life situation.
I wish you an extraordinary day!
