Kanji is a lot harder to learn than it first seems. It can be easy to want to take the approach of just going in and memorizing them by how they look, memorizing what they mean and the stroke order; however, this is a poor place to start.
Radicals need to be learned first. Think of radicals like puzzle pieces, that you can put together to read and write the rest of the kanji! If you are working on learning these, or already have, then you are on an amazing path and will succeed.
I will try and answer your question, but I'm not entirely sure what you're asking. I apologize for that.
Kanji can be written messily. It can be written so messily that parts can blur together. However, strokes must be accurate. Every stroke is identifiable, and every one is unique. Substituting one stroke for a simpler one is rarely worth it. For example, if I used the letter v instead of the letter u in words, while they do look similar, it would be extremely awkward and hard to read.
This kanji is made using the two parts 一 and 木. The strokes on the left and right side of 木 do need to curve slightly, as the radical shows. Try and copy the kanji and radicals as closely as possible - it does matter, as it is how it is written.
Kanji can be one of the hardest things to learn, but you can do it! Soon, it will be easy to write them beautifully and accurately. Practice makes perfect, and we believe in you!
