Life hack: how to almost always have an umbrella when you need one
Practical problem: you go somewhere, like work or school, when it is not raining so you do not bring an umbrella, but when you leave, it is raining and you want an umbrella.
Related problem: you predict it will rain, so you take your umbrella to work (or school), but it does not rain and you accidentally leave your umbrella at work. The next morning, it is raining, but you do not have your umbrella because it is at work.
Related problem: it is raining when you leave for work, so you use your umbrella. When you leave work, it is not raining, and you accidentally leave your umbrella at work. The next day, you need it again but you do not have it.
Solution: own multiple umbrellas and each umbrella has a “home”.
Illustration: you have an apartment, a job, a rented locker at your gym, and a car. Purchase four umbrellas and assign one umbrella to each location. If you think it will rain later, you do not need to remember to bring an umbrella if you will be in one of those four places because if it starts raining, you will have an umbrella with you. If at any time, one location has two umbrellas, you only need to remember to take the extra umbrella back to its “home”. This system means you rarely have to predict the weather, and it means you do not have to remember where your one umbrella is. The most difficult thing you have to do is to not store more than one umbrella in one location: much easier.
Marketing idea for umbrella manufacturers
Very few people currently use the above idea. If umbrella manufacturers ran a coordinated advertising campaign to encourage people to do the above idea, then they could sell multiple umbrellas to each person. Furthermore, they could sell multiple styles of umbrellas. People would probably want a compact umbrella for their gym locker but a larger umbrella for work so that they could keep their work clothes dry. Companies could sell umbrella sets and coordinated colors and patterns.
Since the idea would increase umbrella usage (less people forgetting their umbrella), a follow-up campaign could focus on selling upscale, fashionable umbrellas at premium prices. Brand name designers would even get involved at that point. Fashion-conscious customers would purchase multiple umbrellas to match different clothes and events.
