I would agree with everyone...it is entirely personal but I think there are basically four choices
1 Trace a particular name
2 Trace only direct line ancestors i.e. 4 grandparents, 8 g grandparents, 16 gg grandparents etc.
3 Trace a particular generation i.e. great grandparents
4 Trace everyone with a connection to any of your families
If you choose any theme I think you would have to be very single minded not to stray into one of the other choices. This hobby is a bit like gambling, you see a line of research that will take you back another hundred years and you just have to follow it to see where it leads.
One thing I would urge, is to keep detailed notes and keep the notes in some sort of order. At first you can keep all the names in an ordered manner in your brain but two or three months along the line you will be saying to yourself "I came across that name a month ago but where did I find it?" Jotting down names is fine but always add the source such as Baptism Reg, Holy Trinity, Anytown: Wessex Archives.
Always, always go back to the original source i.e. local certificate, parish register (not bishop's transcript), original will etc. Do not accept other people research or transcriptions, you will usually find it riddled with inaccuracies and errors. Just have a look at the threads running on Rootschat to see the number of errors that have crept in to people's research. Every day I see people saying things like "it must be him, he's the only one of that name in the parish." Months or years down the line, they find someone with the same name in the nextdoor parish and realise that they have wasted hours of research.
Finally, never be afraid to ask for help. You will find no better site than Rootschat for this.
Best of Luck!
