This is coming from a (hopefully) budding writer here, so these by no means apply to everyone.
1) Never set a time limit. These, in my case, make the writer freeze up and hit blocks more often. A good example of this is my chapter 3 of "Mark Steelheart." I promised it at the end of January, and here we are a week into February and it is so close to being finished, and yet it isn't.
1-a) There are some people out there who thrive on haveing a time limit. But it is rarely a good idea to try and force writing.
2) Go to an enviroment that will help you work on that scene. For me, this might mean waiting until I go to school so I can write a happy or hopeful scene. Or going outside, which for me is a rual area, to write a contamplative secene.
2-a) Work with what you have. This is key.
3) Listen to music. For me this means instumental songs, but I often listen to songs that fir the mood of a scene for insperation.
3-a) Use earphones. This way you can listen in one ear only if desired, or turn it up to block out other sounds.
4) If there is a fighting or action heavy scene, it might be helpful to act out that scene. Imagination is an artists best friend.
4-a) Don't be afraid to make a small fool of yourself. If you have to though, find somewhere private to act out those scenes.
5) Write it how you would like to read it. If you like it in choppy sentences, write it like that. If you are more into reading formal writing, write it formal.
5-a) this is by no means applicable to all people, so this is more a personal preferance than the others.
6) Always take critism as a means to improve yourself. Make an effort to use it to your advantadge.
6-a) There will almost always be a hater out there. These people are the exception, and should either be ignored or reported if they harass you about writing something they don't approve of.
7) Almost all writing is for personal satisfaction. Whether it comes from getting comments or just for the sack of writing.
8) A writer can ALWAYS improve their writing. If someone says they can't get better, that is a bold-faced lie. There is nothing stopping you as a writer from improving.
So here are my views on writing. This applies to novice writers (like me) who are just starting out, and the proffesionals who've been writing for years.
If you think one of these is wrong, leave a comment (no haters please) If one can be improved, leave a comment.
If you have made it to here, thank you for reading my opinion.
