In the end, you may also express your appreciation to your family, friends and relatives who supported you in the course of writing a thesis.
It is normal to thank your family and friends, but make sure that your writing is formal.
Usually, acknowledgements vary by length, depending on a number of people whom you’d like to express your gratitude to.
Well, it is understandable that the first person whom you are grateful for something is you and you alone, but think about it once again.
As it was already mentioned, it isn’t a standalone project because you have your adviser who controls your work process and gives you some pieces of advice (sometimes, he doesn’t, but it doesn’t mean that you have not to mention him or her in your acknowledgements), you may ask your peers or friends to take a look at the first draft of your thesis, your friends may give you some useful ideas and advises that you may use in your project.
