The best vectors in our daily life are: 
i. Forces (All pushes/pulls, Weight, etc.)
ii. Displacement

- When you want to push or pull an object, like a grass cutter or a trolly bag, its better keep the force direction at an angle of 45degrees with the ground, so the components of the force equally help to move in horizontal direction as well as the vertical component help to oppose its weight.
- if you want to lift or hold an object, we should apply a force in the opposite direction of its weight. Weight always acts towards the center of the earth, once we know the centre of gravity of the object, it is easy to lift or balance it by applying force on that point. 
- If you have good understanding of the difference between distance and displacement, You will never feel difficulty to find the way in a big city or anywhere.

- Also you can use it when you swim across a river to reach at the aim, you should direct ahead of that point.
